Nắp Ninja Blast Blender (Ninja Blast Blender Cap)

My wife recently bought the Ninja Blast blender, and wanted to keep the blades covered while the other parts are being washed or drying. This is a cap that uses the locking mechanism to stay in place.

There's a notch for the printing seam and to align with the arrow on the Ninja Blast. Simply push the cap in when the notch/line is a bit over 45 degrees to the right of the arrow then twist to lock after the cap has been fully pushed in.

It should be a fairly snug fit so if there is any play after twisting the cap in, I recommend very slightly increasing the size of the print.

STEP file is there for further edits.
